Steam train back on tube track for 150-year anniversary celebrations

Test run for London Underground's anniversary sees restored locomotive pull Victorian carriage from Earl's Court to Moorgate

Pedantically, of course, steam has never run on the tube and is not doing so now, as technically the tube refers to the deep lines, not to the shallow cut-and-cover lines such as Earl's Court to Moorgate. But to most ordinary Londoners, and probably most tourists, the entire London Underground system is known as the Tube.
